DF3DZ-15P-2H(21) Equivalent & Substitute Parts

Part Overview

The DF3DZ-15P-2H(21) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle board-to-board or cable applications. This 15-position connector operates at 0.079" (2.00mm) pitch with a 3A current rating and operates across -55°C to 105°C. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the DF3DZ-15P-2H(21) is determined by the following critical parameters:

Pitch - Mating: 0.079" (2.00mm) — mechanical compatibility with mating connectors
Number of Positions: 15 — circuit connectivity requirement
Number of Rows: 1 — physical layout constraint
Mounting Type: Surface Mount, Right Angle — PCB assembly compatibility
Shrouding: Shrouded - 4 Wall — mechanical alignment and polarization
Termination: Solder — assembly process compatibility
Contact Type: Male Pin — mating interface specification

The identified substitutes meet these core parameters. Variations in current rating, voltage rating, operating temperature range, contact material, and fastening type are permitted within the scope of equivalent substitution, provided the application requirements do not exceed the substitute's electrical or thermal specifications.

Engineering Selection Recommendations

DF3EA-15P-2H(21) — Direct Hirose equivalent within the DF3 series. Maintains identical pitch, position count, mounting configuration, and operating temperature range. Product status is Active with higher inventory availability (1172 pcs). Includes solder retention feature and 250VAC voltage rating. Recommended as primary substitute for direct replacement in existing designs.

S15B-PH-SM4-TB — JST PH series alternative. Meets core mechanical and electrical substitution criteria with identical pitch, position count, and mounting type. Operating temperature range is reduced (-25°C ~ 85°C) and current rating is lower (2A vs. 3A). Voltage rating is 100V. Product status is Active with highest inventory (3061 pcs). Suitable for applications within the reduced thermal and current specifications. Contact shape differs (square vs. circular) and fastening type is Detent Lock rather than Push-Pull.

Selection between DF3EA-15P-2H(21) and S15B-PH-SM4-TB depends on application thermal requirements, current demands, and mating interface compatibility. DF3EA-15P-2H(21) is preferred for applications requiring the full -55°C to 105°C operating range or 3A current capacity.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-15P-2H(21) be used as a direct replacement for DF3DZ-15P-2H(21)?

A: Yes. Both connectors are Hirose DF3 series with identical pitch (0.079"), position count (15), row configuration (1), mounting type (surface mount right-angle), shrouding (4-wall), and operating temperature range (-55°C to 105°C). The primary difference is product status; DF3EA-15P-2H(21) is Active while DF3DZ-15P-2H(21) is discontinued.

Q: What are the limitations of S15B-PH-SM4-TB as a substitute?

A: The S15B-PH-SM4-TB operates within a reduced temperature range (-25°C to 85°C) compared to the original part (-55°C to 105°C). Current rating is 2A versus 3A. Voltage rating is 100V versus 250VAC on the DF3EA variant. Contact shape is square rather than circular, and fastening type is Detent Lock instead of Push-Pull. These differences require verification against application specifications.

Q: Are all three parts RoHS compliant?

A: Yes. DF3DZ-15P-2H(21) and DF3EA-15P-2H(21) are RoHS Compliant. S15B-PH-SM4-TB is ROHS3 Compliant. All meet environmental compliance requirements.

Q: What is the packaging difference between DF3DZ-15P-2H(21) and DF3EA-15P-2H(21)?

A: DF3DZ-15P-2H(21) packaging is not specified in available data. DF3EA-15P-2H(21) is supplied in Tape & Reel (TR) format. S15B-PH-SM4-TB is also supplied in Tape & Reel (TR) format.

Q: Can the fastening type difference affect compatibility?

A: Fastening type (Push-Pull vs. Detent Lock) affects mating connector selection and disconnection force characteristics. DF3DZ-15P-2H(21) and DF3EA-15P-2H(21) use Push-Pull fastening. S15B-PH-SM4-TB uses Detent Lock. Mating connectors must be compatible with the selected fastening mechanism.
